4.7.16
The Sony/Philips Digital Interconnect Format (SPDIF) data is sent using the bi-phase marking code. When
encoding, the SPDIF data signal is modulated by a clock that is twice the bit rate of the data signal.
Table 80
including the timing of the modulating Rx clock (SRCK) for SPDIF in Rx mode and the timing of the
modulating Tx clock (STCLK) for SPDIF in Tx mode.
